PLANT FOR DISPOSAL OF SEWAGE.

SPEC FIC ON forming-part of Letters Patent No. 726,513, dated April 28, 190 3.

Application filed August 13,1902. Serial No. 119,559. (No model.)

To ctZZ whom it may concern:

Be it known that I, JOSEPH DANNER, a citizen of the United States, residing at Scranton, in the county of Lackawanna, State of Pennsylvania, have invented certain new and useful Improvements in Plants for Disposal of Sewage, of which the following is aspecification.

This invention relates to an improved plant for the disposal of sewage; and it comprises a receiving-chamber having a porous floor and divided into several compartments, into one of which the sewer-pipe empties, a dryingchamber adjacent to the receiving-chamber and into which the sediment from the receiving-chamber is conducted, and suitable furnaces in the drying-chamber for drying the sediment and destroying the obnoxious gases. The plant is designed to continuously dispose of the matter discharged from sewer-pipes by first filtering the liquid from the solid material, permitting the former to escape in a clarified and unobnoxious state, while the latter is conducted into the drying-chamber and is there consumed. Air passage-ways are arranged to provide a continuous circulation of air through the receiving-chamber and drying chamber and into the furnace, so that all odors and gases must pass into the furnace-chamber. The plant here shown is in some respects similar to the one illustrated in my Patent No. 672,614, dated April 23, 1901. The present invention comprises improvements in a plant of the same general description as the one shown in the said patent.

In the accompanying drawings, Figure 1 is a plan view of a plant constructed according to my present invention. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation. Fig. i is a rear elevation. Fig. 5 is a central section through the receiving and drying chambers, and Fig. 6 is alongitudinal section through the drying-chamber on the line 6 6 of Fig. 1.

Referring to the drawings, A indicates the receiving-chamber, and B the drying-chamher, both consisting of suitable brick inclosures separated a short distance from one another. The receiving-chamber is provided with a porous floor 1, raised above the base 2 of the chamber. This floor may be composed of brick or other suitable porous material. The chamber is divided into three compartments 3, 4, and 5 by partitions 6 and 7. The sewer-pipe 8 enters the chamber near the top of the settling-compartment 3, as shown, and delivers the sewage upon the porousfioor within said compartment. A communicating opening 9 is formed between the compartments 3 and 4 in the partition 6, and a similar opening 10 is formed between the compartments 4. and 5 in the partition 7. The bottom of the opening 9 is arranged slightly below the mouth of the sewer-pipe, and the bottom of the opening 10 is arranged a little lower than thebottom of the opening 9, the arrangement being such that should the compartment 3 fill with liquid nearly to the sewer-pipe the liquid will flow into the compartment 4 and when the latter is filled nearly to the level of the liquid in the compartment 3 it will flow through the opening 10 into the compartment 5. Opposite the sewer-pipe a short distance above its lower edge is arranged an air-con duit 11, leading into the upper portion of the drying-chamber, and in the side walls of the compartment 5 are formed suitable air-inlet openings 12, the arrangement being such that air entering at the openings 12 will pass through the openings 10 and 9 and the conduit 11 into a drying-chamber, thus providing a circulation of air through the receivingchamber and preventing the escape of gases therefrom to the atmosphere. These openings 12 extend slightly below the opening 10, so that in case the compartment5 should become. filled with liquid to the level of said openings it will flow outward, and thus prevent'the chamber from becoming at any time filled to the level of the sewer-pipe.

In operation a large proportion of the liquid'entering the settling-compartment 3 will filter through the floor of said compartment, while the sediment will be retained therein. As the porous floor in this compartment will in time become clogged, the water rising in the compartment 3 will flow into the compartment 4, but will not carry with it a very large percentage of sediment. In this latter compartment what sediment is carried over will settle, While a large part of the liquid will filter through the porous floor. Should this compartment become filled with liquid, the overflow will pass into the compartment 5, carrying practically no sediment. In the lastnamed compartment the liquid will in ordinary operation filter through the porous floor; but in case of a general clogging of the floor from an excessive flow of sewage or neglect in cleaning out the chamber the liquid will flow through the openings 12, which serve for the admission of air as Well as for the outlet of fluid. Openings 13 are provided beneath the porous floor, through which air may circulate for the evaporation of water from the porous floor and also to permit the filtered Water to pass out. The water after passing through the porous floor is comparatively clear and free from odors and may be conducted away and permitted to soak into the earth. A pipe or passage-way 14is arranged between the compartmant 3 and the drying chamber, said pipe being arranged at about the level of the floor of said compartment. This pipe is provided with a valve 15, which is normally closed. After the plant has been in operation for some time and a considerable amount of sediment has accumulated in the chambers 3 and 4 the flow of sewage through the sewer-pipe is stopped by closing the valve 8 and the valve is opened, permitting the sediment to pass or be forced through the pipe 14 onto the porous floor 16 of the drying-chamber. The several compartments of the receiving-chamber are provided with suitable manholes 17 for convenience of access, and valve-controlled openings 18 are arranged in the lower parts of the partitions 6 and 7, through which any sediment which may accumulate in the chambers 4 and 5 may be shoveled into the chamber 3 and from thence through the pipe 14into the drying-chamber. Access may be had to the space between the porous fioor 1 and base 2 by means of a suitable door 18.

The drying-chamber, as shown in Figs. 5 and 6, is provided at one end with a small furnace 19 and at its opposite end with a larger furnace 20 and a stack 21 to create a suit-abledraft. The porous fioor 16 is raised above'the base, as in the receiving-chamber, in order to provide an air-circulated space beneath the floor. The pipe 14 enters the dryingchamber a short distance above the floor, and the air-conduit 11 enters the upper portion of the chamber. A communicating opening 22 between the drying-chamber and the furnace-chamber 20 is arranged a short distance above the porous floor in order that the air-currents within the receiving-chamber will pass close to the material which is to be dried on their way to the furnace. The larger furnace 20 and stack 21 are for the purpose of creating a draft and consuming the gases. From the furnace 19 heat is supplied for drying the material, and the gases from this furnace are drawn directly over .furnace 19.

the material into the larger furnace-chamber. The draft for the furnace 19 is supplied through the stacks or flues 25, which are provided with openings 26 below the grate of the The draft created by the larger furnace 20 draws air through the flues to the smaller furnace 19. Ordinarily the entire plant will be inclosed by a housing 27, as indicated in Fig. 4, to prevent freezing in cold weather, and any gases escaping within the housing will be drawn down through the fines 25 and consumed.

It will be understood that it is only occasiohally necessary to move the sediment from the receiving-chamberinto the drying-chamber, and it is therefore unnecessary to constantly maintain fires in both furnaces. It is only for the purpose of quickly drying the material that the two furnaces are employed. At other times it is preferable to keep sulficient fire in the larger furnace only in order to create a draft and consume the gases. Openings 24 are provided for the purpose of permitting air to circulate beneath the porous floor 16 for the purpose of evaporating any water which may filter through said floor when material is first brought into the drying-chamber.

It will be seen that in this plant there can be no passage of gases to the atmosphere except through the stack and that as the filtering-chamber is divided into several compartments arranged in a series the filtering operation will be greatly facilitated. While Ihave shown three such compartments, it will be apparent that other compartments might be added, if desirable; but in practice I have found three to be enough, as the liquid upon reaching the third compartment does not contain sufficient sediment to clog the porous floor.
